ZIiI-"ECIFCATION forming part of Letters Patent No. 306,649, dated October 14, 1884.

Application filed November 9, 1883. (No modell To all whom t may concern:

Be it known that I, WILLIAM H. SHoLL, of Hobart, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Springs for Vehicles, of which the following is a full, clear, and exact description, thatA will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The object of my invention is to provide a spring that is light, simple, and durable, and which is adapted to be attached to vehicles of various forms, but is more especially intended for side-bar buggies, and may be attached to the corners of the bodies 0r the center ends.

The nature of this invention consists in constructions and combinations, the arrangement and operation of which will be hereinafter more fully set forth in detail.

Figure 1 is a vertical longitudinal section, in part, of avehicle, showing the construction and arrangement of the spring; and Figs. 2, 3, 4, 5, and 6 are detached sectional details of construction.

Referring to the drawings, A represents the spring, which is made of a single piece of metal and bent around itself in the middle to form the coiled body a of the spring, as shown in Fig. l of the drawings. The two arms B B project in the same direction from the coiled body, but are widely separated. The upper arm extends upward, and is slightly curved vnear the end, which terminates in the T- shaped head c. The lower arm, B', may lie in a horizontal plane or decline a little from a right line, as practical working may seem to require, the curved end terminating in a flattened shape in accordance with the part to which it is to be attached. For instance, if the end of the lower arm is to be attached to the head-block or frontvaxle, it will be of the shape shown in Fig. 2, while for attachment to the rear axle the end will be of the shape shown in Fig. 4. The flattened end a2 is perforated'for the reception of the retaining-bolts b b', and the king-bolt C forms the axis of oscillation. The bolts b l/ stand away from the axle, so as to permit of a'pivotal action of these parts, butare bent inward at the head and attached by means of the screws c3 at. When the lower spring-arm is to be attached to the rear axle, it will be made in the form shown in Fig. 4, and be secured in place by means of a suitable clip, C', passing down over the top ofthe axle and through the clamping-plate b2, by which means the end of the spring-arm is clamped between the plate and the under side of t-he rear axle, as shown in Fig. l of the drawings. The box D is secured to the under side of the bodyF of the vehicle, and provides a suitable bearing for the play of the round T- shaped head of the upper spring-arm.

Fig. 5'shows a transverse section of the box and head of the spring-arm in -the plane 5 5, Fig. 6; and Fig. 6, a longitudinal section in .the plane 6 6, Fig. 5, which fully illustrates the relative position and arrangement of these parts. The heads of the spring-arm B maybe lubricated through the oil-passage d.

As shown in Fig. l of the drawings, two springs are made use of, being placed in the center and at each end of the body-box5'but, if necessary, four springs can be employed and placed at the corners. The inner ends ofthe springs are connected by means of the reach F, which is composed of a single piece of metal coiled in the center to form the springloop d', the ends from thence passing underneath the body of the springs, and being secured to the lower arms just back of the coiled body by means of the clips d2. This arrangement serves to equalize and regulate the movement and action of the springs relative to each other. By this form of construction and arrangement a spring is provided that is light, cheap, and durable, and which readily and easily yields to lessen the iar incident to inequalities in the road.

I am aware that a coiled spring having one end pivoted to the frame and the other end rigidly attached to the body is old. My device differs from that form, in that one end of the spring is pivoted to the body and the other rigidly attached to the axle. construction all danger of the spring being wrenched from the bottom is obviated, as the pivoted end will permit sufficient play of the y parts, Whereas when the end of the spring is rigidly attached to the bottom of the body every movement of the latter makes a wrenching strain upon the attaching device, which if the bottom be made of weak material will be pulled out.

By this'95 Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The co1nbination,with the body and axle of a wagon, of a spring;` coiled near its center, and having one end rigidly attached to the axle, and the other pivoted to the under side of the body, substantially as described.

2. The combination,with the body and axle of a wagon, of a projecting spring coiled near its center, and having one end rigidly attached to the forward axle by the king-bolt and bolts I) and b, and its other end pivoted to the bottoni of the body, substantially as described.

3. vThe combination, with two or more 15 tions therefrom, and attached to the lower 2o arms of the springs A, substantially as set forth.
